I'm trying to spawn a test vehicle i'm trying to make but it spawns in the air

I try to spawn a vehicle that I'm making for beamng.drive using the introduction to vehicle creation guide. When I spawn a vehicle it spawns on the ground like it should but then when I spawn the vehicle that I made, it spawns in the air. WhenI replace the vehicle I already have with the one I made but then it never loads, The game just shows that it is loading the vehicle

Here is the file

As you can see I have only finished the info.json and the jbeam file. I am trying to make a simple jbeam for a cube in blender so I have the right idea of how to make a jbeam

 

The file format for the jbeam is jbeam.jbeam, you should fix that. And I think you formatted some things wrong, there are misplaced brackets

 

Ok, should I just copy the jbeam file from the guide and paste the nodes and beams in again and rename the jbeam file?

I tried redoing the jbeam file I still have the same problem. Here is the link for the zip with the redone jbeam file.

The interesting thing is that when I use ctrl to use the node grabber and trace my mouse around it is in the outline of a Gavril Pickup. I'm really confused now.

Feel free to try to edit the tug.zip and try to fix it.
